Q

What kinds of patients are more susecpitble to adrenal crisis?

A

It should be considered in patients who have a history of:

-Known primary adrenal insufficiency
-Hypopituitarism (any known pituitary hormone deficit or clinical features indicating increased risk), or
-Previous or current prolonged course (2-4 weeks) of steroid therapy

Adrenal crisis may also be the first presentation of underlying adrenal insufficiency or there may be a history suggestive of chronic hypoadrenalism
